In many sinks a device is provided at the end of a flexible tubing through which either clear water or water mixed with a 4liquid detergent may be diverted to facilitate dishwashing. One of the problems involved in such structure is to provide satsifactory valving.

It is ancbject of this invention to provide such a device which is relatively reistant to initial opening but which once this original resistance is overcome, is rel- -atively easy to open further and hold open.

Still a `further object of this invention is to provide novel means for introducing detergent into the water stream flowing therethrough.

Other objects and advantages will be readily apparent from the following description:

This invention is `an improvement to the device described and claimed in prior United States Patent No. 2,795,460.

The device in general comprises a hollow shell or body lll having a water inlet at one end 12. :and an outlet at the opposite end ld. A lever 16 actuates the water control valve 18 to open or close off flow of water and a push but-ton 2l) actuates the detergent control valve 22 to admit detergent to water flowing through the structure. At the inlet end l2 an internally threaded hos-e connector 24 is provided into which a male hose connector (not shown) on a water supply tube may be screwed. A sleeve 26 has one end thereof crimped as at 28 to secure same to connector 24. The lwater control valve 18 which will be described in detail is housed within sleeve 26. Said sleeve has a tube 3d projecting through an opening 32 therethrough which tube is beaded as at 34 to prevent passage of same through opening 32.

The tube 30 is telescopically received within the reservoir sealing member 3d which has -a tubular extension 3S projecting therefrom for this purpose. Telescopically received likewise within said extension 38 is a tube 4t) having an externally threaded nipple 42 at the end thereof with a pair of projections 44 which abut against brush holder 46.

The brush .holder has an outwardly turned flange which overlies shoulder 43 on brush base Sil in which bristles 52 are secured. A nozzle 54 having a central aperture 56 screws onto nipple 42. A rubber spray .forming nozzle 58 lits over nozzle 54 having a series of line holes 6th therein ilow through which creates a Spray.

Thus water iiow is from connector 2d through valve 18 into tubing 3l), tubular extension 38, tubing 40, nipple 42, aperture S6 in nozzle 54 and holes oil in nozzle 53.

Turning now to water control valve 18, a valve hous-` ing 612 has a hollow tubular extension 64 which projects through washer `66, resilient washer 63 and bore 7d into connector 24. A spring 72 surrounds the extension 64 and abuis washer 66 and housing 6?..

Positioned within housing 62 is a resilient valve member 74 which normally abuts the extremity of tubing 3l) and blocks off water flow therethrough. The valve member is mounted in housing 62 by a spider 76 the legs of which abut internal shoulder 7 S of the housing.

A cup shaped valve retainer tlslidably lits on tubing 39 and abuts spider 76. A resilient washer 82 is positioned between retainer Sil and rigid washer 84 which in turn abuts inturned llange 86 on housing `62 securing the valve member 74 in the housing.

Lever 16 at its foremost extremity has a slot 8S which receives projection 90 on liner retainer 9,2. The lever ,also has a pair of yhooks 94 which engage -inturned ilanges 96 on sleeve 26 which sleeveihas the lower forwardmost portion thereof cut away as .at 93 to receive the pivoting lever.

Extending between hooks 94 is a toggle 169. The toggle has an upwardly faced U-shaped section 1492, which receives tube 30, and a pair of downwardly turned legs 104 terminating in outwardly projectingjends 106 which project through holes 108 in hooks 94.

As seen in FIGURES 2 and 3 when the trigger or lever 16 is released, spring 72 urges control valve 1-8 tothe right against toggle Idil untilivalve member 74 abuts .the end of tube 3d. When the handle or body lll is grasped and lever 16 depressed the spring 72 resists movement of valve 18 which `spring can be of sufficient. resistance to avoid accidental or too rapid opening resulting in an unwanted spray of water.

After the initial reluctance of the spring is overcome and as toggle llli is further pivoted counter-clockwise in FIGURES 2 and 3 by further depression of lever I6 the mechanical advantage increases so that further opening of the valve requires less force.

When the valve 18 has traveled to its fully open position as seen in FIGURE 4, the .toggle lo@ and specifically legs 162 have `assumed almost a straight line relationship with spring 72 reducing the force necessary to apply to lever lo to hold the valve fully open. When the lever annex/ie 16 is released, spring 72 pivots same to the initial or open position with valve member 7d again abutting tube 3).

In this embodiment, liquid detergent is stored in a reservoir between body lll) and tube d@ and same is designated lid. This reservoir is closed at one end by nozzle 54, brush holder 46 and packing i12 in conjunction with nipple 42 and at the other end by sealing member 36. The member 36 is formed of -a circular flange lll@ having a series of parts llt? punched therethrough to which tia/nge extension 35i heretofore describe-d is connected. An opposed similar circular flange lid is provided having a tubular extension l2@ thereon'which extension surrounds Ytubing 30 and is spaced therefrom, A resilient liner 122 is provided within extension 12d which surrounds same. The outermost portion of extension 12d is necked inwardly to clamp one extremity of liner to tubing 30. The remaining `end of liner 122 projects between ilanges 114 and 118 and is beaded to form a seal for the reservoir. Tube 3l) and extension 120 each has a hole 12d and 126 therein which latter hole contains a ball 127. A leaf spring member 123 has a central bore through which tube 30 passes and an upper arm i3d which bears against the upper surface of extension l2@ and a lower arm 132 which bears against ball 123 urging same to push a portion of liner T122 into hole 124 lto prevent flow of detergent into tube 30. Button 2li has a pair of legs such as i314 depending therefrom which straddle tube Btl and extension 12h and is notched as at 136 to fit into complementary notches in arm 132. When the button Ztl is depressed the arm E32 is likewise depressed through legs i3d .releasing the spring pressure on ball 127 which then permits the liquid detergent to be drawn from the reselvoir into theV stream of water llowing through tube 3@ until button 2l) is released and ball 127 is again seated in hole 124.

It is to be noted that the lever lo and button are positioned on opposite sides of body lll and in sufticient proximity to permit them to be operated by one hand of the user.

While what hereinbefore has been described is the preferred embodiment of this invention, it is readily apparent that alterations and modilications can be resorted to without departing rJfrom the scope of this invention.
